Application filed July 23, 1915, Serial No. 41,470. Renewed March 19, 1917. Serial No. 155,949.

To all 'whom t may concern.'

Be it known that I, EMIL BOMMER, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates to improvements in and relating to spring hinges, and more particularly to that type of spring hinge known as a vertical floor surface spring hinge, such for example as the devices shown in the patents issued to me on March 16th, 1915, namely, No. 1,131,659 and No. 1,131,667, and has for its object to provide a hinge of this character which Vis positive in action and simple in construction, and which may be adjusted so as to make the tension of the spring greater or less as desired. A further object is to provide in such a hinge improved eXtraneous means for making inoperative the spring action thereof while the door is in open position, such means being adapted to automatically return to normal spring-acting position when the door is closed.

Vith these and other objects in view, my

invention is shown in the accompanying drawings and will be hereinafter more fully described with reference thereto and finally pointed out in the claims.

Fig. 11 is 'a sectional view taken on the line 11-l1 of Fig. 7; and

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, and more particularly to Fig. 1 thereof,a hinge-frame 2O is provided, of rectangular design, preferably having the outer side thereof rounded, as at 21, and provided with an upwardly eX- tending member 22 at the outer side thereof and an inwardly extending member 22a at the lower side thereof, said extensions having screw holes 23 therein for securing the said frame to a suitable recess provided in the corner of the door by means of screws 24. The upper and lower ends of the frame are preferably of circular formation, as at 25 and 26, and are provided with bearings 27 and 28, the said bearing 27 being provided with a flanged portion 29, Fig. 6, bei

neath which are disposed antifriction balls 30. A central shaft or spindle 31 is journaled in the said bearings, said Vspindle being provided with enlarged ends 32 and 33, the end 32 being preferably provided with a rounded upper surface 32a for retaining the antifriction balls 30 within the said flanged portion 29. The lower end of the enlarged portion 33 is squared, as at 34, and the said squared portion rests within a correspondingly shaped socket 35 secured to the floor, thereby retaining the said spindle in stationary position, and preventing movement of the same with the swinging of the door.

Arcuate recesses 36 and 37 are provided in the said enlarged ends 32 and 33 respectively of the spindle, each of the said arcuate recesses extending about half-way around the said enlarged portions', and being about diametrically opposed to each other. A collar 38 is arranged on the enlarged end 32, and is provided with a flangedportion 39 having a plurality of radial openings 40 eX- tending therethrough, and is also provided with an opening 41 extending through the said flange and at right angles to the openings 40, and in whichis disposed the upper end of a helical spring 42. A similar collar 43 is provided on the enlarged end 33, and having a flanged portion 44, in which is arranged a single radial opening 45 and an opening 46 at right angles thereto, in which is disposed the other end of the said spring 42. A pin 47 is provided in the said collar lOO 43, extending through the opening 45 thereof, and into the arcuate recess 87 of the spindle. rlhe outer end of the said pin extends outwardly from the said collar, and is adapted to abut against the transverse face 48 of a projection 49 provided at the lower end of the frame 20, the opposite side of the said projection being beveled, as at 49a.

A pin 50 is also provided in the collar 38, extending through one of the openings Ll() thereof, and into the arcuate recess 36 at the upper end of the spindle V31, the outer end of the said pin abutting against the transverse face 51 of a projection 52 provided at the upper end of the said frame, the opposite face of the projection being beveled, as at 5P, but the bevel being oppositely disposed to the bevel of 49a. lt will be seen that by changing the pin 50 from one of the opeL ings et() to another, that the tension of the spring l2 may be made greater or less as desired. At the upper end of the door, there is preferably provided a socket 20a, in which is disposed a preferably spring-pressed` plunger 2Ob of the door frame for pivotally holding the upper end of the door in position.

ln swinging of the door, the operation of this embodiment of my improved hinge is as follows z- Vihen the door is swung to the right for instance, the pin 47 at the lower end of the spindle 3l, which pin 47 abuts aga-inst one end of the arcuate recess 37 and against the lower projection 49 of the hinge-frame 20, permits the movement of the collar l?) with the door. The lower projection 4:9 forces the collar i3 to rotate about the lower end of Lthe spindle 31 by means of the pin `i7, which is free to move in this direction in the arcuate recess 37 to the other end thereof. The upper projection 51 is moved away from the pin 50; the spring is thereby tensioned, and when the door is released, it returns the saine to normal or closed position. When the door is openedy in the other direction, however, the action is reversed, the upper collar l-l. in this case moving with the hinge-frame, by reason of the pin 5() abutting against one end of the recess 86, the pin 50 being free to move in the recess 86 to the other end thereof, the collar 38 rotating about the upper end of the spindle by means of the projection 5l abutting against the pin 50 andl moving the same with the hingeframe. away from the pin 47.

In F ig. 7, l have shown a modied form of my invention, in which means are incorporated for making the spring inoperative when it is desired to have the door remain in open position. In this construction, a frame 53 is provided similar in shape to the frame 20 of the foregoing construction, and

1 having bearings 5t and 55 at the upper and rlhe lower projection i8 is moved ynazaire lower ends thereof, in which are journaled ed on the spindle 56, resting at its lower endon the shoulder 6l ,formed by the enlarged portion 58, and a flange 62 is provided at the upper end thereof, and the intermediate portion is recessed as at 63. At the lower end of the sleeve, an arcuate cut-out portion 64 is provided extending preferably about half-way around the same.

Beneath the flange 62 is provided an arcuate recess 65 also extending preferably about half-way around the sleeve, b'ut about diainetrically opposed to the said cut-out portion 64. A collar 66 is provided at the upper end of the sleeve 60, having a flange 67 fitting beneath the flange 62 of the said sleeve, the said flange 67 being provided with a plurality of radial openings 68 extending therethrough, and also with an opening 69 at right angles to the openings 68, and in flange 7 2, which rests upon the lower portion of the hinge-frame, said flange being provided with a single radial opening 73 and an opening 7a at right angles thereto, in which is disposed the other end of the said helical spring 70.

A pwin 75 is provided in the collar 7l, extending through the said opening 73 and into the arcuate cut-out portion (Sil of the sleeve, the outer end abutting against the transverse face of a projection 76 provided at the lower end of the hinge-frame. A pin 77 is also provided in the collar 66 extending through one of the openings 68 thereof and into the arcuate recess 65 of the said sleeve, the outer end thereof abutting against the transverse face of a projection 78 provided a-t the upper end of the hinge-frame, the projection 78 being oppositely disposed from the said projection 76.

Keyed to the upper end of the spindle 56 by means of a pin 79 is aloclringmeinber 80, which overhangs at its forward portion the flange 62 of the sleeve 60, and in this overhanging portion there is provided a hole 8l, in which is disposed a springpressed plunger 82, which engages a recess 82a provided in the periphery of the flange 62, and rests against the upper surface of the collar 66. A portion of the plunger, however, overhangs the collar 67. A for- Cv n llt)

lifting the same.

For enabling the operation of-this lifting member, a second plate 87, upon the upper edge of which the lower edge of the balanced lifting plate 84 movably rests, is disposed beneath the said plate 84, and is proyso ' spring to again be operative.

vided with a fo-rwardly extending wedgeshaped projection 88, which is movable within a slot 89 of the frame. The plate 84 is provided at its lower end with a forwardly extending projection 84a to form a forwardly extending seat for the lower end of the spring 94, Fig. 12.

Pivoted to the said frame beneath the projection 88 are two pivoted levers 90 and 91 extending at each side of the hinge and provided with inclined surfaces 92 and 93, which engage the inclined faces of the wedge-shaped projection 88, and upon depression of either of the said levers, will cause the said projection and the plate 87 to be lifted, thereby lifting the upper plate 84 and the projection 83 carried thereby,

, which causes the plunger 82 to be forced into the hole 81, whereupon the door may be operated without spring power, and the plunger will be carried out of register with the recess 82L of the flange 62 and will engage the uppersurface of the flange 62, thereby permitting the collars 66 and 71 to be moved with the door in either direction, and causing the spring to be inoperative during this movement. It will be seen that 'upon closing of the door, the plunger 82.

will again engage the recess 82a of the flange 62tliereby locking the same to the member 80 and to the spindle 56, and causing the For returning the lifting member to its normal position, a spring 94, Fig. 12, is provided within a recess 95 of the member 84, and engages at its upper end a projection 96 of the recessed portion 85 of the frame, and engages at itslower end a forwardly extending projection 84L of the member 84.

A cover plate 97 is secured over the said recess 85 for holding the parts of the lifting mechanism in position, said plate being preferably provided at its lower end with two downwardly extending projections 98 and 99, which engage corresponding recesses 100 and 101 in the hinge-frame, and the upper endthereof is preferably provided with a hole 102, through which a fastening screw `103 may be secured to the frame. The spring 94 also serves to press the plate 84 with its member 83 forward into contact position with the plunger 82, the lower edge of plate 84 having a forward projection 84a to seat the lower end of the spring 94 thereon somewhat forward of its upper` end.

The operation of this form of my improved hinge, excepting the spring-actuated plunger 82 for connecting and .disconnecting the coil spring 70 and the mechanism .actuating said plunger 82 above described,

is exactly the same as that described with reference to the first embodiment when the spring is in operative position, the sleeve 60 when locked to the shaft or spindle 56 performing the same function as the shaft 31 of the first embodiment.V
